The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.

The present disclosure relates to coated non-metallic substrates and coated metallic substrates, and methods for producing such coated substrates. A variant of the method is characterized in that a mat or glossy coating is underneath a metallic layer obtained in some cases by way of vapor deposition and/or sputtering. In another variant, the metallic is sufficiently thin so that it remains transparent or translucent to visible light. The coated substrates may include multiple layers such as metallic layers, polysiloxane layers, a color layer, a conversion layer, a primer layer, and/or a transparent or colored layer. An application system for applying a metallic layer to at least one surface of a substrate may include a plasma generator and/or a corona system for treating one or more layers by plasma treatment and/or corona treatment.

A composite panel having a plurality of carbon plies, a perforated metallic foil comprising several apertures and being directly secured to the plurality of carbon plies, and a protective layer made from resin reinforced with fibers which is secured to the metallic foil. The perforated metallic foil is embedded in the protective layer through its apertures. A free surface of the protective layer forms a top side of the composite panel. The thickness of the protective layer between the top side of the composite panel and the perforated metallic foil is at least 15 micrometers and the perforated metallic foil has a thickness of not more than 30 micrometers. The plurality of apertures in the aggregate defines an open area of not more than 40% of the surface area and a maximum distance between two opposed points in a perimeter of an aperture is equal to or less than 3 mm.

A steel part includes a steel sheet substrate and a coating on at least one surface of the steel sheet substrate. The coating includes between 0.2 and 0.7% by weight of Al, with a remainder of the metal coating being Zn and inevitable impurities. The steel sheet substrate and the coating have at least one deformation. An outer surface of the coating has a waviness Wa.sub.0.8 of less than or equal to 0.43 μm.

A process for manufacturing corrosion resistant metal components is disclosed. The process comprises abrasive blasting of a silicon-containing steel substrate followed by hot dip galvanizing, a second abrasive blasting process, treating with a mineral acid, and coating with a polymeric coating. The resulting corrosion resistance is enhanced.

A coated metal sheet includes a steel substrate and a coating on at least one surface of the steel substrate. The coating includes between 0.2 and 0.7% by weight of Al, with a remainder of the metal coating being Zn and inevitable impurities. The coated metal sheet was subjected to a skin pass operation after coating. An outer surface of the metal coating has a waviness Wa.sub.0.8 of less than or equal to 0.55 μm.

A polyurea comprises at least urea base units of formula —NH—CO—NH— and additional units. The additional units comprise at least, on the one hand, a secondary alcohol functional group and, on the other hand, an ether, thioether or secondary amine functional group in the alpha position with respect to the secondary alcohol functional group. Such a polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example, glass or metal, to an unsaturated rubber or as corrosion-resistant protective coating for a metal substrate. Metal reinforcers, such as thread, cord, film or plate, coated can also be coated with such a polymer.

The present invention provides for an inorganic nanostructure-organic polymer heterostructure, useful as a thermoelectric composite material, comprising (a) an inorganic nanostructure, and (b) an electrically conductive organic polymer disposed on the inorganic nanostructure. Both the inorganic nanostructure and the electrically conductive organic polymer are solution-processable.

The invention relates to an aluminum alloy strip with improved surface optics, which is fabricated via hot and/or cold rolling, and consists of a type AA 3xxx, AA 5xxx, AA 6xxx or AA 8xxx aluminum alloy. The object of proposing an aluminum alloy strip that is suitable for attractive and precious surface optics despite the elevated percentage of alloy constituents is achieved in that, after degreasing, the finish-rolled aluminum alloy strip exhibits an increase in the luminance value L*(ΔL) in relation to the rolled-greasy state of more than 5 while measuring the color of the surface in the CIE L*a*b* color space using a standard illuminant D65 and a normal observation angle of 10°, excluding direct reflection in 45°/0° geometry.

This relates to a process for manufacturing a recovery annealed coated steel substrate for packaging applications and a packaging steel product produced thereby.
